Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the present invention provides a municipal manhole cover, which solves the problem that the traditional manhole cover is easy to be rolled down to the ground, causing damage to the road surface, and after the heavy rain, impurities will block the manhole cover and need to be cleaned manually, which cannot be actively dredged. capacity, which is not conducive to the problem of flood discharge and drainage of municipal roads

Embodiment 1

[0035] Such as Figure 1-3 As shown, the present invention provides a technical solution: a municipal manhole cover, including a storage shell 1, the bottom end of the storage shell 1 is fixedly connected with a mounting base 2, and one side of the top of the mounting base 2 is fixedly connected with a moving shaft 3, The end of the moving shaft 3 away from the installation base plate 2 is rotatably connected with a protective cover plate 4, and the inside of the protective cover plate 4 and the position close to the outside are uniformly provided with drainage grooves 5, and the middle position of the installation base plate 2 is fixedly connected with a limit insertion rod 6, which limits The top surface of the insertion rod 6 is evenly and fixedly connected with the stirring drive rod 7, and the outer side of the storage case 1 is evenly and fixedly connected with the movable slot 8, and the inside of the movable slot 8 is penetrated and slidably connected with a lateral sta...

Embodiment 2

[0038] Such as Figure 4 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: a municipal manhole cover, the lateral stabilizing mechanism 9 includes a stabilizing insertion rod 91, the stabilizing insertion rod 91 runs through the inside of the movable slot 8, and the stabilizing insertion rod 91 A propelling shovel head 92 is fixedly connected to one end outside the housing case 1 . Reduce the pressure of the soil around the manhole cover to avoid the problem of manhole cover sinking.

[0039] One end of the stabilizing insert rod 91 located inside the housing 1 is rotatably connected with a crushing drive tooth 93 , and the crushing drive tooth 93 is arranged correspondingly to the stirring drive rod 7 . The extruding force of the contact can shred the impurities on the 7 surface, avoid the accumulation and blockage of impurities, and realize the active removal of impurities.

Embodiment 3

[0041] Such as Figure 5 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a municipal manhole cover, the auxiliary drive mechanism 10 includes a sealing pump rod 101, the top of the sealing pump rod 101 and the protective cover plate 4 The bottom is fixedly connected, and the bottom end inside the sealed pump rod 101 is penetrated and connected with a transmission rotary rod 102 for rotation. The end and the inside of the stirring drive rod 7 pass through and are threaded.

[0042] One end of the transmission rotary rod 102 located inside the sealed pump rod 101 is fixedly connected with a sealing plug 104 , and an inner conduction pipe 105 is uniformly fixedly connected with the position inside the protective cover plate 4 and corresponding to the drainage groove 5 . The air pressure realizes the buffering of the driving of the vehicle, and the high air pressure generated at the same time provides power for the dre...

Abstract

The invention discloses a municipal manhole cover, and relates to the technical field of manhole covers. The municipal manhole cover comprises a storage shell, wherein a mounting bottom plate is fixedly connected to the bottom end of the interior of the storage shell; a movable shaft rod is fixedly connected to one side of the top of the mounting bottom plate; a protective cover plate is rotationally connected to the end, away from the mounting bottom plate, of the movable shaft rod; drainage grooves are uniformly formed in the position, close to the outer side, of the interior of the protective cover plate; a limiting inserting rod is fixedly connected to the middle position of the mounting bottom plate; stirring driving rods are uniformly and fixedly connected to the surface of the top of the limiting inserting rod; movable inserting grooves are uniformly and fixedly connected to the outer side of the storage shell; transverse stabilizing mechanisms penetrate through the interiors ofthe movable inserting grooves and are connected to the interiors of the movable inserting grooves in a sliding mode; an auxiliary driving mechanism is fixedly connected to the middle position of theinner side of the protective cover plate; a carrying supporting plate is fixedly connected to the position, close to the upper portion, of the inner side of the storage shell; and the carrying supporting plate and the protective cover plate are correspondingly arranged. According to the municipal manhole cover, the air pressure is achieved, so that buffering of vehicle driving is realized, and meanwhile, the generated high air pressure provides power for dredging of the manhole cover.

Description

technical field [0001] The invention relates to the technical field of well covers, in particular to a municipal well cover. Background technique [0002] Manhole covers are used to cover roads or deep wells in homes to prevent people or objects from falling. According to the material, it can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. [0003] As the Chinese invention publication number is: a kind of multi-proof manhole cover of CN101555694A. The multi-well cover is composed of a ring seat (1) and a cover plate (2) that are rotatably connected together. The inner edge of the cover plate support platform (3) is provided with a lock (6), and a lock is provided under the cover plate (2). Tongue (8). When the cover (2) is closed with force, the bolt (8) slides under the buckle (6), so that the ring seat (1) and the cover (2) are locked together, which not only effectively prevents theft, but also preven...
